TO ALL WHOM IT MAY GONCERN: f p i Bejt known that I, DAVID H. IRLAND, ofFayette, iyu the county of Seneca, and State of `New York, have inventeda certain new and useful Improvement in-Gas-Apparatus'g' and I do herebydeclare that the followingis` i a full and exact description thereof,reference being had to the accompanying drawings, making part of thisspecification. l 2

Figure 1 is a perspective view. ot' my-improved apparatus. Figure 2, avertical section ofthe retort andcondensing'eliamber. Figure 3, across-section ofthe condensing-chamber. Like letters of referenceindi-cate corresponding parts in all Vtbe gurcs.v

My improvement relates to a Vportable gas-apparatus, in which the retortis applied to a common stove, so that when the gas has been extractedfrom the coal, the latter can bc utilized for fuel-by-drawng fromtheretort' y' into the stove.

v My invention consists in the construction and arrangement of thecondensing-cylinder, having an elevated ash-pan for catching'soot, and achamber for the contact of the' gas' with water, said'cylinder beingemployed, in connection withjthe retort, purifier, `and gasometelg'ashereinafter set forth. .i A) i In the drawings,'A represents the retort,which may be of any desired form, and connectedwiththe stove i in anydesired manner. It has asuitable door, a, held in place by set-screw bof-re'movable cross-head c.`

Above the retort is situated the condensing-cylinder B, 'the parts beingconnected by pipes C C, which o pen' near the top of cylinder, as ,shownin iig. 2. The condensingeylinder basin its upper part an ash orsoot-pan, l

D, with raised edge or flange d, and partition f, which cuts off thepassage from the induction-pipes C C to v eduction-pipe'E, except in theroundabout 4way indicated by the arrows, ig.'2, in which case the Vgasis brought 'in-contact with water, nearly lling 'the chamber G below`the ash-pan..

r,'.lhc opposite end of pipe E opens into puriiierH, which is filledwith lime, and after the gas is purified, it passes through pipe I intogasometerK, containing Water, from whence it is discharged `in'anysuitable xnanner for utilization. V.

By this connection and construction of the condensing-cylinder, I amenabled to bring the gasin contact with water, to deposit the aqueouselements bcf'ore it reacties the lime-purifier. Such soot as is carriedup from the retort is caught in the elevated ash-pan D, and can be drawnoutat anyV time through -a inanehole in the,

head or side of the cylinder. This soot is prevented from taintingthewater by thelanges df, forming thereby a shallow pan. The gus, inpassing the indirect way indicated by the arrows, becomes in a degreecooled by contact with the cold top ofthe cylinder, so that when itreaches the surface of the water beneath, it is in .that condition tobest deposit tne watery part, which it eiectually does in the-longpassage over the surface of the liquid. I am not aware that acondensing-cylinder thus constructed has ever before been interposedbetween the retort and purifier. i i

What I claim as my invention, and desire to secure by Letters Patent,is;-

,The interposed eondensingcylinder B, c'onstruotedwh the elevated:rsh-pan D1 and water-chamber G, and employed in connection with theretort A, purifier II, and gasom'eter'K', substantially as and for thelpurpose herein set forth.

In witnesswheroI .have hereunto signed my name in the presence oftwosubscribing witnesses.
